CheckBox check;

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);

   check = (CheckBox) findViewById(R.id.checkBox1);
   check.setOnCheckedChangeListener(new OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if(isChecked){
            check.setBackgroundColor(Color.BLUE);
        }else{
            check.setBackgroundColor(Color.BLACK);
        }

Answer 1

You should try this:

checkBox.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(checkBox.isChecked()) {
                    listView.setBackgroundColor(Color.parseColor("#008000"));
                } else {
                    listView.setBackgroundColor(Color.parseColor("#FF0000"));
                }
            }
        });

This should be pretty easy. The checkbox can have a text associated. So simply put the text in the checkbox and give the text a color which is a . In the selector xml you can easily specify the colors for the normal and the checked state.

The code you posted does not show any ListView. So that would be the first problem.

If you're trying to change the row color of a listview, you need to implement getView() of the adapter that feeds the ListView and update the view that is returned appropriately.
